How will an SPI firewall handle a packet containing a TCP segment which is an acknowledgement?

Expert Solution

For a packet that contains a TCPP segment which is an acknowledgement, an SPI firewall will pass it if it is part of the approved connection. If the packet attempts to open a connection, then in must pass the paccket through the Access Control List (ACL), if it passes it will be accepted (approved by the ACL rules), but if it fails, it will be rejected (dropped and logged) The Stateful Packet Inspection (SPI) treats different types of packets in different ways and it depends on the risk of the packet. The most riskiest pack will have more resources spent on it, while the less risky packet will have less time spent on it. .

An SPI firwall will handle a packet containing a TCP segment which is also an acknowledgement by passing it if it is part of the approved connection.
